Abstract:
Objective To investigate the feasibility and cortex activation of fMRI in the aged volunteers during the performance of visuospatial tasks. Methods Visuospatial tasks were conducted in 11 normal aged volunteers. The fMRI data was postprocessed using SPM99 to reveal the activated cortex.Results The visuospatial tasks were fulfilled satisfactorily in all aged subjects. Cortex around the left intraparietal sulcus, dorsolateral cortex in the left prefrontal lobe and bilateral occipital lobes showed activation. We found a selective enhancement of fMRI signal in the left superior parietal lobule. Conclusion FMRI tasks are feasible in the aged people and the left superior parietal lobule is the specific in the visuospatial information processing.
